Abstract: A method for producing an integrated circuit (IC) chip on a semiconductor device wafer is disclosed. In one aspect, the IC chip includes buried interconnect rails in the front end of line and a power delivery network (PDN) on the back side of the chip. The PDN is connected to the front side by micro-sized through semiconductor via (TSV) connections through the thinned semiconductor wafer. The production of the TSVs is integrated in the process flow for fabricating the interconnect rails, with the TSVs being produced in a self-aligned manner relative to the interconnect rails. After bonding the device wafer to a landing wafer, the semiconductor layer onto which the active devices of the chip have been produced is thinned from the back side, and the TSVs are exposed. The self-aligned manner of producing the TSVs enables scaling down the process towards smaller dimensions without losing accurate positioning of the TSVs.

Abstract: An integrated circuit (IC) chip having power and ground rails incorporated in the front end of line (FEOL) is disclosed. In one aspect, these power and ground rails are at the same level as the active devices and are therefore buried deep in the IC, as seen from the front of the chip. The connection from the buried interconnects to the source and drain areas is established by local interconnects. These local interconnects are not part of the back end of line, but they are for the most part embedded in a pre-metal dielectric layer onto which the BEOL is produced. In a further aspect, a power delivery network (PDN) of the IC is located in its entirety on the backside of the chip. The PDN is connected to the buried interconnects through suitable connections, for example metal-filled through-semiconductor vias or through silicon vias.

Abstract: A method for bonding chips to a landing wafer is disclosed. In one aspect, a volume of alignment liquid is dispensed on a wettable surface of the chip so as to become attached to the surface, after which the chip is moved towards the bonding site on the wafer, the bonding site equally being provided with a wettable surface. A liquid bridge is formed between the chip and the bonding site on the substrate wafer, enabling self-alignment of the chip. Dispensing alignment liquid on the chip and not the wafer is advantageous in terms of mitigating unwanted evaporation of the liquid prior to bonding.

Abstract: A package including a first die embedded in a reconstructed wafer obtainable by the known FO-WLP or eWLB technologies is disclosed. In one aspect and in addition to the first die, a Through Substrate Via insert is embedded in the wafer, the TSV insert being a separate element, possibly a silicon die with metal filled vias interconnecting contacts on the front and back sides of the insert. A second die is mounted on the back side of the substrate, with contacts on the second die in electrical connection with the TSV insert's contacts on the back side of the substrate. On the front side of the substrate, a lateral connecting device is mounted which interconnects the TSV insert's contacts on the front side of the substrate to contacts on the front side of the first die. The lateral connecting device and the TSV insert thereby effectively interconnect the contacts on the first and second dies. In another aspect, the lateral connecting device is mounted on a redistribution layer on the front side of the substrate, as it is known from FO-WLP technology.

Abstract: A method for bonding and interconnecting two or more IC devices arranged on substrates such as silicon wafers is disclosed. In one aspect, the wafers are bonded by a direct bonding technique to form a wafer assembly, and the multiple IC devices are provided with metal contact structures. A TSV (Through Semiconductor Via) is produced through the bonded wafer assembly. The IC device or devices in the upper wafer or wafers have contact structures that serve as masks for the etching of the TSV opening. A conformal isolation liner is deposited in the TSV opening, and subsequently removed from the bottom and any horizontal areas in the TSV opening, while maintaining the liner on the sidewalls, followed by deposition of a TSV plug in the TSV opening. The removal of the liner is done without applying a lithography step.

Abstract: Alignment of a first micro-electronic component to a receiving surface of a second micro-electronic component is realized by a capillary force-induced self-alignment, combined with an electrostatic alignment. The latter is accomplished by providing at least one first electrical conductor line along the periphery of the first component, and at least one second electrical conductor along the periphery of the location on the receiving surface of the second component onto which the component is to be placed. The contact areas surrounded by the conductor lines are covered with a wetting layer. The electrical conductor lines may be embedded in a strip of anti-wetting material that runs along the peripheries to create a wettability contrast. The wettability contrast helps to maintain a drop of alignment liquid between the contact areas so as to obtain self-alignment by capillary force. By applying appropriate charges on the conductor lines, electrostatic self-alignment is realized, which improves the alignment obtained through capillary force and maintains the alignment during evaporation of the liquid.

Abstract: A method for producing a stack of semiconductor devices and the stacked device obtained thereof are disclosed. In one aspect, the method includes providing a first semiconductor device comprising a dielectric layer with a hole, the hole lined with a metal layer and partially filled with solder material. The method also includes providing a second semiconductor device with a compliant layer having a metal protrusion through the compliant layer, the protrusion capped with a capping layer. The method further includes mounting the devices by landing the metal protrusion in the hole, where the compliant layer is spaced from the dielectric layer. The method includes thereafter reflowing the solder material, thereby bonding the devices such that the compliant layer is contacting the dielectric layer.

Abstract: Alignment of a first micro-electronic component to a receiving surface of a second micro-electronic component is realized by a capillary force-induced self-alignment, combined with an electrostatic alignment. The latter is accomplished by providing at least one first electrical conductor line along the periphery of the first component, and at least one second electrical conductor along the periphery of the location on the receiving surface of the second component onto which the component is to be placed. The contact areas surrounded by the conductor lines are covered with a wetting layer. The electrical conductor lines may be embedded in a strip of anti-wetting material that runs along the peripheries to create a wettability contrast. The wettability contrast helps to maintain a drop of alignment liquid between the contact areas so as to obtain self-alignment by capillary force. By applying appropriate charges on the conductor lines, electrostatic self-alignment is realized, which improves the alignment obtained through capillary force and maintains the alignment during evaporation of the liquid.

Abstract translation: 第一微电子部件与第二微电子部件的接收表面的对准通过与静电取向相结合的毛细管力诱导的自对准来实现。 后者通过沿着第一部件的周边提供至少一个第一电导体线，以及沿着第二部件的接收表面上的位置的周边的至少一个第二电导体，部件将放置在其上 。 由导体线包围的接触区域被润湿层覆盖。 电导体线可以嵌入沿着周边延伸的防湿材料条，以产生润湿性对比度。 润湿性对比度有助于保持接触区域之间的取向液滴，从而通过毛细管力获得自对准。 通过在导体线上施加适当的电荷，实现静电自对准，这改善了通过毛细管力获得的对准并且在液体的蒸发期间保持对准。
